GUESS & WIN!! Doing these mods next week,how much gain?

You can see in my sig what I already have and I'll be doing these following mods next week, switching from 3.23's to 4.11's, Pacesetter longtubes, custom Y pipe, no cats, Under drive pulley, 52mm tb with air foil, tb bypass, pcmforless custom tune, any guess on rw hp gain? Any guess how this will help my et's, previous best was 8.8 in the 8th..thanks guys!! joe

I have decided to make this a little more interesting. People make posts like the one I made above ALL THE TIME! So here is what I'm going to do. I will take my car to a dyno on Monday in Evansville and get numbers before the mods, then I will preform all of the mods above and return to the dyno for the new numbers. Who ever guesses closest to the actual HP and TQ gain will win a prize package to be disclosed at a later time. This will be a neat little prize package with most likely some kind of Camaroz28.com goodies, stickers, hat, calendar, I'm not sure what yet but it should be fun. I will do a second prize package for the ET gain in the 8th, I will post my best previous ET slip (if I can find it) a little while later, If two people or more guess the same correct answer then I will draw the winner from a LT1 valve cover ..anyone interested?? Or is this stupid??? Joe....PS I think this maybe should be in the lounge....if so, mods please move it..thanks.

Re: Doing these mods next week,how much gain?

Based on what you have said, I think you will drop to a low 8 sec e.t. The 4.10's will kick your ***. The exhaust and throttle body will improve air flow. The LT's will not help your low end though but wont hurt it either. There wont be sufficient backpressure build up.
I think you said you ran 8.8. I will say about 8.3. Im so used to thinking of 1/4 mile. You will pick mph too. You may even see an 8.2. With tuning that helps.
waiting for the results
